Jason df0b2fd469 fix(mcu): MCU-A1 — replace 25 C cooling stub with 70/60 C hysteresis ...

Cooling-fan trip in main.cpp's periodic temperature block was a 25 C dev
stub that latched the fan ON at room temperature on every boot. Replaced
with production thermal control: ON at 70 C, OFF at 60 C. The 10 C
dead-band prevents relay/fan chatter near the threshold; the 70 C ON
point sits below the 75 C SAFE-mode gate in checkSystemHealth() so the
fan engages before the system shuts down.

Driven from the existing `temperature` global (max of 8 sensors,
populated just above by the GAP-3 fix) instead of re-OR'ing the eight
Temperature_N variables — single source of truth, and the diag now
prints the actual peak temperature on each transition.

Added test_mcu_a1_cooling_hysteresis (9 cases) covering cold-start,
upward crossing, dead-band hold, downward crossing, and a regression
guard at 30 C that would have engaged the fan under the old stub.
MCU regression now 77/77.
